Fix Excel Time-Cell Formula Errors in WPS Office Spreadsheets
Question details
The user needs to correct a WIP hours formula that uses CELL, IF, IFERROR, VALUE, and TEXT and returns incorrect results for some time cells formatted as [h]:mm.

- Device & OS
- not provided
- Scenario
- Calculating work-in-progress hours across a row of time cells that appear to use the same [h]:mm format.
- Observed behavior
- The formula returns correct WIP hours for some rows but incorrect results for others, even though the cells appear to use the same [h]:mm format.
Confirm that the time cells contain real time values rather than text by selecting one cell and entering =ISNUMBER(cell). Also check the result cell's number format, because a text-formatted result cell can cause further incorrect display.
Replace CELL format detection with direct time value calculation
Use this fix when your formula relies on CELL("format", range) to test multiple time cells, because CELL does not return an array and cannot reliably identify the [h]:mm custom format.
CELL("format",G3:R3) evaluates only the first cell in the referenced range and may return "G" for [h]:mm cells, so any IF/IFERROR branch based on that result can treat remaining cells incorrectly.
If the cells already contain valid Excel or WPS time values, you do not need to inspect the number format. Add or sum the values directly and apply the [h]:mm format to the result cell.
Click the cell where the WIP hours total should appear, such as the first output cell next to the row that currently returns incorrect results.
Type =SUM(G3:R3) and press Enter. If the values are valid time serial numbers, this sums the hours and minutes directly.
Right-click the result cell, choose Format Cells, click Custom, and enter [h]:mm so totals over 24 hours display correctly.
Copy the formula down or re-check the affected rows; they should now return the same correct WIP hours as the other rows.
Fix Time-Cell Formula Errors in WPS Office Spreadsheets
Use WPS Office Spreadsheets to calculate WIP hours directly from time values, without relying on Excel's CELL format detection. Apply a simple SUM formula and the [h]:mm custom format to get accurate totals across all rows.
- 1. Open your workbook in WPS Office Spreadsheets: Launch WPS Office, click Open, and select the Excel workbook that contains the WIP hours formula.
- 2. Select the WIP hours result cell: Click the first cell where the total hours should appear in the row that currently returns incorrect results.
- 3. Enter the SUM formula: Type =SUM(G3:R3) and press Enter to calculate the time values directly.
- 4. Apply the [h]:mm custom format: Right-click the result cell, choose Format Cells, click Custom, and enter [h]:mm to display elapsed hours correctly.
- 5. Copy the corrected formula down: Use the fill handle to copy the formula to the remaining rows and confirm all WIP hours totals are consistent.
Frequently Asked Questions
Why does CELL("format",G3:R3) only check the first cell?
CELL does not return an array over a range; it evaluates only the top-left cell of the referenced range. Therefore it cannot test each time cell individually, which explains why some rows appear wrong even with the same [h]:mm format.
What number format should I use to show WIP hours over 24 hours?
Select the result cell, right-click, choose Format Cells > Custom, and enter [h]:mm. The square brackets keep hours from resetting at 24.
Can I still use IFERROR and VALUE with time cells?
You can, but avoid wrapping the CELL format test around them as a row-level condition. If the cells contain real time values, use =SUM(range) directly; only use VALUE or TEXT when you are importing text that must be converted.
How do I check if a cell is a valid time value in WPS Spreadsheets?
Select the cell and change its format to General; a valid time appears as a decimal between 0 and 1, while text remains text. You can also use =ISNUMBER(cell) to verify.
